I have a 5971 that I pulled out of storage a few months back and have posted about here a few times. Overall, it has worked well, or at least it did after sitting under vacuum for a week or two.
I noticed this when I gave it a once over before putting it into service, though-rather than the one piece ion focus lens I've seen on every other 5971 I've serviced, this one is in two pieces-a cylinder and then just a flat plate with a hole in the center. Both are nested into the same slot in the vespal insulators, and there's a springy gold-plated wire that goes between them.
Has anyone encountered this construction before? It seems to work fine, but is also a bit of a pain to put back together.
